Based on the user's download request, the data transmission can neither affect the user's normal online access nor limit the user's download speed.

Further refer to FIG. 4 , which shows a flow 400 of another embodiment of a method for sending data based on a user download request. The flow 400 of the data sending method based on the user download request includes the following steps:

Step 401, receiving a download request from a user.

In this embodiment, the electronic device (such as the server shown in FIG. 1 ) on which the data transmission method based on the user download request runs can receive the download from the terminal through which the user requests the download through a wired connection or a wireless connection. request, wherein the above-mentioned download request includes information about the file to be downloaded, user information of the above-mentioned user, and download start time.

Step 402, determine the user's download speed limit according to the user information.

In this embodiment, based on the download request obtained in step 401, the above-mentioned electronic device (such as the server shown in FIG. 1 ) may first obtain the user information corresponding to the above-mentioned download request; then determine the user's download limit according to the above-mentioned user information. speed.

Step 403, determine the unlimited speed buffer download amount according to the file information to be downloaded.

In this embodiment, based on the download request obtained in step 401, the above-mentioned electronic device (such as the server shown in FIG. 1 ) can first obtain the information of the file to be downloaded corresponding to the above-mentioned download request; Unlimited buffered downloads.

Step 404, in each sending cycle, judge whether the amount of data sent is less than the amount of downloadable data.

In this embodiment, in each sending cycle, the electronic device judges whether the amount of data sent is less than the amount of downloadable data, and if the amount of data sent is less than the amount of downloadable data, go to step 405; if the amount of data sent is not less than downloadable data volume, go to step 406.

In this embodiment, the amount of downloadable data can be calculated by using Formula 1:

cdSize＝nolmtSize+lmtVDld*(curTm–bgTm) (Formula 1)

Wherein, nolmtSize is the unlimited speed buffer download amount determined in the above step 403, lmtVDld is the download speed limit determined in the above step 402, curTm is the current time, and bgTm is the download start corresponding to the download request received in the above step 401 time, cdSize is the calculated amount of downloadable data.

For example, for a download request starting at 8:00:00 on January 6, 2016, the determined download speed limit is 1MB/s, the determined unlimited buffer download volume is 5MB, and the current time is January 6, 2016 If the current time is 08:00:2 on January 6, 2016, the downloadable data cdSize is 7MB.

Step 405, sending data to the user in this sending cycle.

In this embodiment, the above-mentioned electronic device may send data of a sendable data amount to the user in this sending cycle, wherein the sendable data amount may be calculated by using Formula 2:

csSize＝cdSize–aSize (Formula 2)

Wherein, cdSize is the downloadable data volume calculated in step 404, aSize is the transmitted data volume, and csSize is the calculated transmittable data volume.

In step 406, no data is sent to the user in this sending cycle.

In this embodiment, the above-mentioned electronic device may no longer send data to the user, and after waiting for the required waiting time, go to step 404, wherein the above-mentioned waiting time is calculated using Formula 3:

tWait＝(aSize–cdSize)/lmtVDld (Formula 3)

Wherein, aSize is the amount of data sent, cdSize is the amount of downloadable data calculated in step 404, lmtVDld is the download speed limit determined in step 402, and tWait is the calculated waiting time.

Step 407, in each sending cycle, record the amount of data actually sent in this sending cycle.

In this embodiment, the above-mentioned electronic device can record the amount of data actually sent in this sending cycle. Due to the different receiving speeds of users, the user may not receive all the data sent to the user in this sending cycle. Periodically record the amount of data actually sent in this sending cycle.

Step 408, in each sending cycle, update the sent data amount with the sum of the sent data amount plus the actual sent data amount in this sending cycle.

In this embodiment, the above-mentioned electronic device can first obtain the amount of data sent, and then obtain the actual amount of data sent in this sending cycle recorded in step 407, and then use the sum of the amount of data sent plus the amount of data actually sent in this sending cycle to update The amount of data sent.

As can be seen from FIG. 4, compared with the embodiment corresponding to FIG. 2, the process 400 of the data sending method based on user download request in this embodiment highlights that in each sending cycle, it is judged whether the amount of data sent is less than the available data. Step 404 of downloading the amount of data, step 405 of sending the data of the amount that can be sent to the user, and step 406 of not sending data to the user until the waiting time is required. Therefore, the solution described in this embodiment can more effectively control the speed of data transmission, so as to more effectively implement data transmission based on the user's download request without affecting the user's normal online access and limiting the user's download speed.
